好朋友。我使用Spring-web,-mvc等版本4.1.x和spring-secure版本4.0.0,我有一个奇怪的问题。

我有LoginController.java和@RequestMapping(" / login")返回"登录",映射到login.jsp。我还有带有下一个设置的security-config.xml文件

<security:authentication-manager>
    <security:authentication-provider>
        <security:user-service>
            <security:user name="John" authorities="admin"
                           password="letmein" />
            <security:user name="Zog" authorities="admin"
                           password="iamzog" />
        </security:user-service>
    </security:authentication-provider>
</security:authentication-manager>

<security:http use-expressions="true">
    <security:csrf disabled="true"></security:csrf>
    <security:intercept-url pattern="/createoffer" access="isAuthenticated()" />
    <security:intercept-url pattern="/docreate" access="isAuthenticated()" />
    <security:intercept-url pattern="/offercreated" access="isAuthenticated()" />
    <security:intercept-url pattern="/" access="permitAll" />
    <security:intercept-url pattern="/login" access="permitAll" />
    <security:intercept-url pattern="/static/**" access="permitAll" />
    <security:intercept-url pattern="/offers" access="permitAll" />
    <security:intercept-url pattern="/**" access="denyAll" />

    <security:form-login login-page="/login"
                         login-processing-url="/login"
                         username-parameter="username"
                         password-parameter="password"
                         default-target-url="/"
                         authentication-failure-url="/login?error=true"/>
</security:http>

当我尝试打开/登录时,弹出显示默认登录表单,我的LoginController方法不会执行。但是当我在这个登录表单中输入错误的数据时,spring会将我重定向到/ login?error = true并且LoginController捕获这个并重定向到我的login.jsp。所以,spring在我的控制器之前捕获/登录,但是传递/登录?error = true到控制器并且我的自定义登录表单没有正常工作。

我的web.xml文件如下所示

来自春季课程网站的人提出同样的问题,但唯一的答案是使用spring-security 3.x.x&#39;。我不想使用3x安全性,但想要了解弹簧的魔力在哪里被打破。谢谢你提前。

这是Spring Security 4中的一个错误,记录为SEC-2919。它将在Spring Security 4.0.1中修复,将于下周发布。

<强>变通方法

以下是一些解决方法。您可以在4.0.1发布后删除解决方法(预计大约一周)。

使用其他网址

最简单的解决方法是使用&#34; / login&#34;以外的网址。例如,您可以使用&#34; / authenticate&#34;。

<http ...>
    <form-login login-page="/authenticate" ... />
</http>

使用BeanPostProcessor

或者,以下BeanDefinitionRegistryPostProcessor将通过删除DefaultLoginPageGeneratingFilter来解决问题。要使用它,只需确保将BeanDefinitionRegistryPostProcessor注册为Bean。

例如,创建一个类似于以下内容的类:

package sample;

import java.util.Iterator;
import java.util.List;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.beans.factory.support.BeanDefinitionRegistry;
import org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor;
import org.springframework.security.web.DefaultSecurityFilterChain;
import org.springframework.security.web.authentication.ui.DefaultLoginPageGeneratingFilter;

public class Sec2919PostProcessor implements BeanDefinitionRegistryPostProcessor {
    @Override
    public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry registry)
            throws BeansException {
        String[] beanDefinitionNames = registry.getBeanDefinitionNames();
        for(String name : beanDefinitionNames) {
            BeanDefinition beanDefinition = registry.getBeanDefinition(name);
            if(beanDefinition.getBeanClassName().equals(DefaultSecurityFilterChain.class.getName())) {
                List<Object> filters = (List<Object>) beanDefinition.getConstructorArgumentValues().getArgumentValue(1, List.class).getValue();
                Iterator<Object> iFilters = filters.iterator();
                while(iFilters.hasNext()) {
                    Object f = iFilters.next();
                    if(f instanceof BeanDefinition) {
                        BeanDefinition bean = (BeanDefinition) f;
                        if(bean.getBeanClassName().equals(DefaultLoginPageGeneratingFilter.class.getName())) {
                            iFilters.remove();
                        }
                    }
                }
            }
        }
    }

    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)
            throws BeansException {
    }
}

然后添加bean定义:

<bean class="sample.Sec2919PostProcessor"/>
